Hi Max, MF and Glo Mod Gadge,
Just an update as I decided to still have another crack at it tonight in the shade after dinner instead of out in the hot sun tomorrow.
Well I got the larger bearing puller set on to it and pulled up some serious tension, then using a small Thor Copper hammer and a solid steel block on the other side against the boss I gave it a few solid taps and suddenly it let go. All I had to do then is wind it up and off she came as easy as that.
Yes the square pull off the bearing puller jaws is far more of a positive even force opposed to a 3 jaw puller.
Cleaned it all up and now the boss slides on and off by hand just nicely like it would've done when it was first assembled by Victa.
Oh and not to forget, a good lashing of Loctite Silver Anti-Seize prior to assembly always helps for later on when the need arises.
Again thanks for all the suggestions, as we got a great result in the end.
Cheers,
BB.
